The debate will rage on but Novak Djokovic believes he is the best player in the modern era after claiming a record-equalling 20th Grand Slam title by beating Italy's Matteo Berrettini in the Wimbledon final on Sunday.
By adding a sixth Wimbledon title to the second French Open he won last month and the ninth Australian crown he earned in February, the 34-year-old Serb has put together a sensational year which has moved him alongside Roger Federer and Rafa Nadal at the top of the list of men's Grand Slam winners.
With Swiss Federer close to his 40th birthday and Spaniard Nadal, 35, having lost his grip on Roland Garros after losing to Djokovic this year, the Serb is destined to forge ahead.
"I consider myself best and I believe that I am the best, otherwise I wouldn't be talking confidently about winning slams and making history," Djokovic, who withstood the ferocious firepower of Berrettini to win 6-7(4) 6-4 6-4 6-3 in a fever-pitch atmosphere on Centre Court, told reporters.
"But whether I'm the greatest of all time or not, I leave that debate to other people. I said before that it's very difficult to compare the eras of tennis.
"We have different rackets, technology, balls, courts. It's just completely different conditions that we're playing in, so it's very hard to compare tennis from 50 years ago to today."
Djokovic declared himself "honoured to be part of the conversation" but the evidence is stacking up in his favour after his third successive Wimbledon title.
